I really need help with this please!

sloppy joe

Step-by-step explanation:

1. Mixture A

2. y=10

so,x= 4 on solving equations

so 10 would consume 4 spoon in mix B

while 10 would consume 8 spoon in mix A

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
